With a discharge (Q) of 290ML during the day of this photo, and more than 400ML the previous day, Yabba Falls is quite a spectacle. Due to difficult access, these falls are not much known. This is one of the first published modern photographs of Yabba Falls. I am aware of three historical photos taken in c.1900, 1913 and 1963. The total fall of c500ft/150M includes a series of drops beginning with the vertical plunge into the plunge pool, rapids, chute (2nd falls) and bottom cascades. Yabba Creek rises on the Conondale/Jimna Ranges and descends through forested areas flowing NNW towards the South Burnett catchment at first. After flowing past the forestry township of Jimna it begins to meander through a granite area that has been cleared for cattle grazing. At Yabba Station, this upper section of Yabba Creek then turns at right angles into hard metamorphic rocks and drops over Yabba Falls and heads towards the Mary River. Yabba Falls therefore represents the point at which the Yabba's headwaters were captured from the Burnett Catchment. Such stream captures are significant in the zoological history of the Mary River ecosystem, for the Yabba/Mary is home to the (now endangered) Mary River Cod, a species very closely related to the cod of the inland rivers of the Murray-Darling catchment.
